【问题描述】：

此装备是从目录中插入的。当玩家没有装备时，它会通过点击缩略图将玩家重新定位到地图的中心。在第 1 次，我在自己制作的游戏中进行了测试。每次我卸下它时，玩家都会不断地从底板上掉下来并死去。我注意到它一遍又一遍的位置相同。我将底板的位置向下移动，玩家倒在底板上而不是死去。然后我在一个新的空底板中测试了装备，卸下装备，玩家也移动到了中心。我检查了手柄和玩家躯干的位置，但该轴与脚本中的任何位置都不匹配。有人可以为我指出这一点，以便我可以将其更改为玩家停止的最后位置吗？

【问题讨论】：

您可以尝试删除这个吗？ Humanoid.PlatformStand = false

我把三个破折号“---”放在前面，让它成为一个注释，以防它不是它。我玩过它，它仍然在未装备时将玩家移动到地图的中间。我取出（评论它们）“Humanoid.PlatformStand = false”和“Humanoid.PlatformStand = true”。还是不行。

【参考方案1】：

我找到了。 Freezingplayer是罪魁祸首。我在“Spawn(FreezePlayer)”没有装备的时候拿出了它，它可以工作。
